(57) [Abstract] [Purpose] To develop a scent-imparting molded product that can generate a scent over a long period of time to a patterned thermosetting resin molded product. [Structure] A pattern is formed on a thermosetting synthetic resin substrate with an adhesive layer if necessary, and a scent layer is formed on the pattern.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a resin molded product having a fragrance on its surface, and more particularly to a patterned resin molded product that stably generates a fragrance for a long period of time.

[0002]

[Prior art]

 As is well known, resin molded products with patterns are widely used in practice and give a strong visual impression. It would be extremely desirable if this type of molded article could be given an olfactory impact as well as a visual impression.

However, although this kind of resin molded product that produces a fragrance for an extremely short period of time is known, the scent disappears in an extremely short time, and in practice, it is substantially a scented product. Is hard to say.

[0004]

[Problems to be solved by the device]

 Therefore, the problem to be solved by the present invention is to develop a patterned resin molded product capable of stably generating a desired scent over a long period of at least 6 months or longer.

[0005]

[Means for Solving the Problems]

 This problem can be solved by forming a pattern on a thermosetting synthetic resin substrate, optionally with an adhesive layer, and then forming a scent layer on the pattern.

[0006]

[Operation and configuration of the device]

 As shown in FIG. 1, the basic form of the present invention is that a pattern 2 is first formed on a thermosetting resin substrate 1, and a scent layer 3 is formed thereon. At this time, as shown in FIG. 2, an adhesive layer 4 may be formed between the base material 1 and the design 2.

As described above, in the present invention, since the scent layer is formed on the design, in other words, on the surface of the molded article, the scent is generated. At this time, since the powder containing the fragrance added to the organic powder is used, the scent gradually volatilizes, and the scent can be stably generated over a long period of time.

For example, when a rose pattern is formed as a pattern, by forming a scent layer that generates a rose scent, the presence of the rose will be emphasized both visually and olfactoryly.

The thermosetting resin substrate used in the present invention is not particularly limited, and various kinds of thermosetting resins are widely used. The shape of the substrate is not particularly limited as long as it can be molded using a thermosetting resin, and various shapes are widely included. As a typical example, various containers can be exemplified.

As the design formed on this base material, a desired design is appropriately selected and formed. At this time, the design may be a single color or may be formed in two or more colors. The pattern may be formed on the entire surface of the substrate, or may be a part. When the design itself is provided with adhesiveness, it is not necessary to intentionally provide an adhesive layer on the substrate. When the design does not have adhesiveness, an adhesive layer is formed on the base material and the design is bonded onto the base material. As the design, a design made from a flexible sheet or woven fabric can also be used. The means itself for forming the design on the base material is not limited at all, and various means can be appropriately selected and used as long as the design can be adhered to the base material with a predetermined strength.

The scent layer formed on this pattern is usually formed of a composition mainly composed of an organic powder containing a fragrance. Thus, since the fragrance is once contained in the organic powder and the fragrance layer is formed using this, the scent can be gradually and stably generated in the present invention over a long period of time.

In the present invention, when a polyurethane resin is used as the organic powder, for example, diisocyanate, which is a urethane component of the polyurethane resin, may react with the fragrance component. Since it is contained in the powder, a urethane curing reaction based on the diisocyanate occurs before the perfume component reacts with the diisocyanate, and the perfume component remains as it is. As described above, in the present invention, it is important to include the fragrance component in the organic powder. Examples of the organic powder used at this time include powders of organic compounds, preferably various resins.

The scent layer has a thickness of usually 5 to 100 μm, preferably 10 to 50 μm, and particularly preferably 15 to 35 μm. As the fragrance itself, a desired fragrance may be appropriately used, and it is particularly preferable to use a fragrance that matches the formed pattern.

In the present invention, a protective layer may be provided to protect the scent layer. In addition to the function of protecting the scent layer, this protective layer may be more positively added with functions such as non-slip of the surface, polishing or matting. For example, in the case of adding an anti-slip effect, the protective layer may be roughened, for example, the surface may be provided with irregularities, and the polishing may be performed by including a polishing component in the protective layer. At this time, the protective layer is preferably transparent.

[0015]

[Effect of device]

 Thus, not only the pattern (design) but also the scent is imparted to the molded product of the present invention, and the scent is stably exhibited over a long period of time. Therefore, a strong impression can be given to both the sense of sight and the sense of smell.

【Example】

 Hereinafter, the present invention will be described in detail with reference to representative embodiments of the present invention.

[0017]

Example 1 A mold (female mold) preheated to 150 ° C. was filled with urea resin powder, and a male mold heated to 150 ° C. was used to perform press molding at 150 ° C. at 150 to 200 kg / cm ^2. A circular tray-like base material having a diameter of 250 mm, a depth of about 15 mm and a thickness of about 4 mm was formed. Next, I raised the male mold once to remove it, covered it with release paper, and lowered the male mold again to mold. Then, the molded product was taken out and cooled to manufacture a tray-like base material.

On the other hand, 10 g of a two-component polyurethane resin composition containing an organic powder containing a fragrance component was uniformly spray-coated, dried in a room, and naturally cured to form a scent layer. This product generated a stable scent for at least 6 months.

[Correction content]

In the present invention, for example, when a polyurethane resin is used as the scent layer resin, diisocyanate, which is a urethane component of the polyurethane resin, may react with the fragrance component, but the fragrance is mixed with an organic powder. When the powder contained in is used as a scent component , a urethane curing reaction based on the diisocyanate occurs before the fragrance component reacts with the diisocyanate, and the fragrance component remains as it is. As described above, in the present invention, it is important to add the fragrance component to the organic powder. Examples of the organic powder used at this time include perfume-containing organic compounds, preferably porous powders of various resins.
